Ceramic CO2 Diffuser — 40mm Disc

This 40mm ceramic disc CO2 diffuser is a versatile and affordable option for planted aquariums up to 100 litres. The sintered ceramic membrane produces an exceptionally fine mist of CO2 micro-bubbles that dissolve rapidly in the water column, maximising gas absorption efficiency and reducing the amount of undissolved CO2 that reaches the water surface. The diffuser is designed to operate at low pressures suitable for most aquarium CO2 systems, and the acrylic body is easy to clean. A suction cup bracket is included for secure mounting inside the aquarium. Position the diffuser near a filter outlet or powerhead to distribute micro-bubbles throughout the tank for even CO2 coverage.
